The SMC KT-VBA43A-1 Pneumatic Booster Valve is engineered to elevate industrial pneumatic systems by amplifying input pressure up to 2 times (select models up to 4x). Designed for localized high-pressure requirements in low-pressure overall circuits, this valve operates through a dual-chamber reciprocating piston mechanism. Input air drives a piston assembly that compresses air in the chamber, delivering stabilized high-pressure output through a self-regulating pressure control system.

Key Features:

• Dual-Stage Pressure Amplification: Achieves output pressures up to 1.6 MPa (232 psi) with input ranges of 0.2-1.6 MPa
• Precision Pressure Control: Manual adjustment via ergonomic handwheel with built-in pressure relief mechanism
• Compact Integration: Directly connects to VBAT series accumulators for space-efficient installations
• Self-Regulating Design: Automatic pressure stabilization through feedback-controlled exhaust valves
• Low Maintenance: Lubrication-free operation with wear-resistant internal components

Technical Specifications:

• Port Sizes: Rc/G 1/4" to 1/2" (NPT/NPTF optional)
• Operating Temperature: -10°C to 60°C (14°F to 140°F)
• Maximum Flow: 1,900 L/min (ANR)
• Noise Reduction: Integrated silencer with <70 dB(A) emission

Applications:

• High-pressure clamping in CNC machining centers
• Pneumatic actuators requiring localized pressure boosting
• Leak testing systems for automotive components
• Precision spray coating equipment in electronics manufacturing

Installation Notes:

Requires upstream oil mist separator (AM series) and downstream exhaust filter. Maintain minimum 50mm clearance for handwheel operation and servicing.
